For each of the following sets,

a) S={1,2,3}, T ={a, b, c}

b) S={a, b}, T ={1,2,3,4}

c) S={1,2,3,4}, T ={a, b}

Determine whether

1. There is a one-to-one function f:S→T;

2. There is an onto function f:S→T; and

3. If there is a bijective function f:S→T.

4. For each (1–3) if such a function exists, explicitly give it. If no function exists give a short explanation?
